Application filed September 13, 1913.

To all whom it may concern Be it known that I, PHILIP J. MEAHL, acitizen of the United States, and resident of Summit, in the county ofUnion and State of New Jersey, have invented certa1n new and usefulImprovements in Perforating-Machines, of which the followmg 1s aspecification.

This invention relates to improvements 1n perforating machines andparticularly to that class of perforating machines wh1ch are used formaking perforated music sheets to be used in connection withautomatically playing musical instruments, in which perforated musicsheets the slots or perforations are arranged in a series of rows eX-tending lengthwise of the sheet and spaced uniformly transversely to thesheet.

The object of my invention is to provide a new and improved perforatingmachine for the above-mentioned purposes, which is simple inconstruction, effective and reliable in action and by means of whichperforations of different shapes, size, style or character can beproduced successively or alternately in the same longitudinal row ofslots or perforations all in a single passage of the blank sheet to beperforated through the machine.

In the accompanying drawings in which like letters of reference indicatelike parts in all the figures: Figure l is a plan view of my perforatingmachine, parts being broken away and some omitted. Fig. 2 is a verticallongitudinal sectional view on the line aa, parts being broken away.

The machine is constructed with a main frame 1 011 which all the severalparts are mounted. At the center of the main frame two standards 2 areprovided, one on each side, in which is mounted the main drive shaft 3carrying a fly wheel 4; and any suitable means for rotating the shaftfrom a source of power. On this shaft is fixed a cam disk 5 having agroove into which a pin 6 passes, which extends laterally from the topof a vertically reciprocating punch operating head 7 suitably guided inthe side frames of the machine. Beneath the head 7 two transverse punchguides 8 are secured in the side frames, directly above two dieholdingblocks 9 on the top of each of which a die plate 10 is secured. In thepunch guide 8 a series of punches 11 are guided to move vertically, eachpunch being provided at its upper end with a button 12 whichSpecification of Letters Patent.

rests in a recess 13 in the punch operating head 7, so that as the headmoves upward the punches are all raised. Above each button 12 ahorizontal punch controlling slide 1 1- is mounted on edge so that itcan be shifted across the head 7 horizontally and each slide is providedin its bottom edge with a notch or recess 15 into which the button 12 ofthe punch directly below it can pass when said notch or recess is inalinement with the punch. In a bracket 16 at each end of the main frame1, a transverse shaft 17 is mounted on which is secured aperforated-master sheet drum 18 of conventional construction, which drumis provided at its end with sprocket teeth 19 which can pass in slotsout along the edge of the master sheet, in the well known manner. Thisdrum is driven by suitable gearing to be described hereinafter, from themain shaft 3, so that a pre-determined relation is established betweenthe speed of rotation of the main shaft 3 and the drum 18 and for eachrotation of the main shaft, the master sheet drum is rotatively shifteda certain distance. A series of horizontal selector pins 22 are guidedat their free ends by a guide plate 23 adjacent to and parallel with thedrum 18 and the opposite end of each of these selector pins is pivotallyconnected with the upper end of a curved substantially L-shaped liftinglever 24% pivoted at 125 to a bar 28 having a series of vertical slots27 in which said lifting levers 24 are severally located. Each selectorpin is connected above its pivot with one end of a spring 28, theopposite end of which is secured to a bracket 29 on the bar 26, whichsprings serve to pull on the upper ends of the lifting levers, therebygently pressing the free ends of the selector pins against the mastersheet passing over the drum 18, the lower ends of which lifting leverseach terminate in a head 30 resting within a notch 31 of a thrust block32 of which one is provided for each lifting lever, said thrust blocksbeing suitably guided in slots in the bar 26'to move up and downvertically under the action of the lifting levers 24:. Whenever a holeappears in the master sheet opposite the row of guide holes in the guideplate 23 the corresponding selector pin is forced to the right into saidhole in the masier sheet under the action of a spring 28 and thereby thecorresponding thrust block 32 is raised as indicated in dotted lines.

A carriage 33, extending transversely across the machine frame is guidedat its ends in a horizontal guide 34 so as to reciprocate horizontallyand in said carriage one 5 selector rod 35 is mounted for each slide 14and corresponding lifting lever 24, one end of said selector rod beingpivotedly connected with the corresponding slide 14 and the opposite endbeing connected with a U- shaped piece 36 mounted slidably in thecarriage in such manner that the ends 37 of the long shanks of theseveral pieces 36 project beyond the right hand side of the carriage andinto the paths of the several thrust blocks 32 whereas the shortershanks of the U-shaped piece are each connected with one end of a spring38, the opposite end of which is attached to the carriage, which springsthus serve for keeping the ends 37 of the U-shaped piece projectedbeyond the right hand side of the carriage and above the thrust blocks32. The carriage 33 is provided with a laterally proj ecting pin 39which is engaged by the lower forked end of a lever 40 pivoted at 4:1and connected by a link 12 with a plate 43 having a longitudinal slot 44through which the main shaft 3 passes. This plate carries a pin 45 whichprojects into a cam groove 46 of a cam disk 47 secured on the main shaftso that as the main shaft is rotated the lever 40 is rocked to and froand correspondingly reciprocates the carriage 33 toward and from thethrust blocks 32.

The machiueryjust described is at the right hand end of the main frame 1and identically the same machinery is found at the left hand end, butmerely reversed so that each set of dies has its control slides, slidingcarriage and selector pins and set of thrust blocks connected with theselector pins. The paper sheets d8 to be perforated are passed over thedie plate 10 and this paper is shifted by a paper feeding device 49 ofany well known construction. Adjacent to the outer edges and upper endparts of each group of lifting levers 24, at each end of the machine, Iprovide a bar 50 which can swing toward and from the upper parts of thelifting levers and serves as a restoring bar for bringing the liftinglevers 24 and selector pins 22 connected therewith into normal position,once for each rotation of the main shaft. This bar 50 is connected byarms 51 at its end with a rock shaft 52 extending transversely acrossthe machine, which rock shaft is operated by a bar 53 from a cam 54: ofany suitable construction on the main shaft A shaft 55 is driven bysuitable gearing of any suitable kind from the main shaft 3 and I preferto use for this purpose the Geneva star wheel so well known in machinesof this kind, that it is not necessary to illustrate or describe it. Theshaft 55 at one end carries a bevel cog the opposite end the shaft 55carries a bevel cog wheel engaging two diametrically op posite pinions61, each on a shaft 62 parallel with the sides of the machine, whichshafts 62 each by means of a worm 63 drives one of the master sheet drumshafts 17.

represents a table which supports the paper passing over the die plates.

71 represents the master sheets.

The operation is as follows:The master sheet must be so arranged thatone master sheet controls the punches of one row of punches and theother master sheet controls the punches of the other row and the mastersheets must be so arranged and spaced. that the punches of each row ofpunches will be operated at the proper time. For exau'iple, if the righthand row of punches makes large holes, the left hand row of punchesshould make small holes, or holes of another shape. If in one of thelongitudinal lines of perforations in the paper sheet there are to bethree successive holes made by large punches and the last one of theseis to be followed by nine successive individual punchings of small holesand the paper moves from right to left, the master sheets are soarranged that the three successive large punchings are punched by one ofthe punches of the right hand group, the cone spending punch of the lefthand group remains idle until finally the three holes made by a punch inthe right hand group have passed beyond the left hand group of puncheswhereupon the correspondingpunch in the left hand group is operated therequired number of times under control of the corresponding mastersheet. lVhenever a. hole in the master sheet comes in line with acorresponding hole in the plate 23 the corresponding lifting lever 24raises its thrust block 32. The machine is so timed that the 11 passingof the selector pins into the master sheet and the lifting of thethrust; blocks can only take place when the right hand carriage 33 hasbeen moved to the left so that the projecting ends 37 of the U-shapedpiece 36 are out of the way of the rising thrust block and when then thesaid right hand carriage moves to the right the ends 37 corresponding tothe raised thrust blocks will strike against the raised thrust blocks,whereby the ends 37 and the corresponding U-shaped parts 36, rods 35 andslides 14: are all pushed to the left so that the recesses 13 in thecorresponding slides 14 are no longer over the punch buttons andconsequently the corresponding punches are depressed when the punch headdescends. For each rotation of the main shaft the paper is fed forward apredetermined distance, the punch head being raised. The carriages 33are moved toward the center of the machine and at the same time therestoring bars 50 are swung from the lifting levers to permit some ofthe selector pins to pass through the holes in the master sheet wherebythe corresponding thrust blocks are raised. Then the carriages 33 aremoved toward the thrust blocks and the ends 37 encounter the front edgesof the raised thrust blocks whereby the corresponding slides 14 arepushed toward the center of the machine and solid portions of the slidesare above the corresponding punch buttons and then the punch headdescends and forces those punches over which there are solid portions ofthe slides 14 through the paper. The punch head rises, the carriages 33are moved toward the center of the machine again and the restoring bars50 are swung toward the center of the machine thereby withdrawing theselector pins that have passed into the holes in the master sheet andbringing all the thrust blocks into normal position and so on for eachrotation of the shaft.

As has been pointed out, the corresponding punches in the two groups arein line so that one punch of each group can make a perforation in oneand the same line or row of longitudinal rows of punchings in the sheet.The times at which the punches are depressed are controlled entirely bythe arrangement of the slots in the master sheets and from the mastersheet through the selector pins, lifting levers, thrust blocks,reciprocating carriages and the slides 14:, the selection and operationof the punches are thus controlled.

The master sheet drums 18 are provided with rows of holes as indicatedon the right hand drum in Fig. 1 but the balance of these holes havebeen omitted to avoid confusion.
